@Hootenanny. About Walter's house.

In the OP Pseudonymous referred to it a as a 'farmhouse' and was suggesting that Walter's family was better off than the authors of some accounts sought to present. In a later posts he refers to it looking "Much more like a farmhouse than a mere farm cottage" and says "Time after time I read he live in a farm labourers's cottage".

So I checked what was shown in the film against Google Earth/Streetview. The film opens with and lingers on a larger house that is on the other side of the road. From above (the satellite view) I interpret Walter's house as having been ancilliary to a substantial farm.

My bad for using the term 'farm labourer's cottage'. None of the writers who's words are found on Mustrad call it that. I find it slightly prejudicial. Mike Yates or Rod Strandling say 'farm workers cottage'.

I live in a village for which local historian put together a house-by-house account cross-referenced to census records at a time when living memory went back to 1900. Families were packed incredibly tightly in small houses, children were boarded out with neighbours. An unmarried lady slept for years behind a curtain on a landing (the one I am sitting on at this computer). Farm workers rented houses had pig-sty's and they worked large vegetable gardens and some had a few animals.

So, contrary to the angle presented in the OP, the descriptions of Walter and his family - and what you and Jim say about his house - seem to me very credible for carpenter in a rural village.
